Fang Yong commented on FLINK-6511:
----------------------------------
Thank you for your reply [~till.rohrmann], It's sound good! I noted that all
the methods in {{JobClient}} are static, in my mind there may be some changes
in JobClient as follows:
1. Create non static methods that are consistent with the current static ones
in {{JobClient}}
2. Add {{close}} method in {{JobClient}}
3. Create instance of {{BlobCache}} in {{JobClient}}, and close it when the
{{JobClient}} is closed
What do you think of it? Looking forward to hearing your suggestion, thanks :)

> The {{JobClient}} creates a {{BlobCache}} to download user code jars from the
> {{BlobServer}} when trying to retrieve the user code class loader. This
> {{BlobCache}} won't be properly closed, though. I think it would be better to
> instantiate a {{BlobCache}} in the {{JobClient}} and close once the
> {{JobClient}} is being closed.
